PRODUCT ADVANTAGES

• Simultaneous carbon dioxide and water determination with minimal sample preparation
• Analysis of TOC (Total Organic Carbon) and TIC (Total Inorganic Carbon) without adding acids
• Rapid, precise, accurate and reliable element determination
• Up to 5 programmable steps with different temperatures (“ramps”) can be defined
• Wide range of materials can be analyzed
• Resistance furnace temperature can be set up to 1000 °C in steps of 1 °C
• Customized infrared cells provide wide, dynamic measuring range
• Due to gold IR path, increased cell life time for analysis of halogen or acid containing samples
• Powerful software (multilingual, customized display, export of results)
• Single and multipoint calibration
• No halogen trap required
• Electronic gas flow control
• Low maintenance
• Robust design allows usage in production control and laboratory

APPLICATION EXAMPLES

Gypsum, cement, limestone, minerals, ores, soil, slag, waste

FUNCTIONAL PRINCIPLE

Operation of the CW-800M is simple and convenient. After weighing the sample in a quartz boat, it is placed on the loading mechanism of the furnace. In the following, the analysis can be started and the boat is introduced into the furnace by the user. Depending on a user defined program, different temperatures and carrier gases are applied to the sample. While processing this program, the released CO2 and water is determined by the infrared cells. The received “chromatogram” of the sample subsequently shows different fractions of carbon and water of the sample. All data processing, control of the combustion process and calculating of the result is done by an external PC. The duration of the measurement depends on the length of the user defined steps. A common analysis takes about up to 20 minutes.
